This pedal packs the Green Rhino Overdrives beloved stampede of gritty, gnarly overdrive into a super pedalboard-friendly housing. Smallest of the herd, but it unleashes tones that rivals its larger companions. The Volume, Tone, and Drive controls cover the basic functions, while the Freq and Curve controls offer finer adjustment of your beastly sonic yield. The Freq control cuts or boosts at either 100Hz or 500Hz – set internally – while the Curve control allows you to soften the creatures roar if it gets too aggressive. With this level of versatility, you can take any amp from pristine to punchy, from dirty to thunderous. MFSKU WM22 UPC 710137122215
